| cleptohaematophagy of the triatomine bug belminus herreri. | the triatomine bug belminus herreri, previously known only from panama, is reported for the first time from colombia. three adult b. herreri were collected from a chicken coop and a viable egg was found on a bactris palm at carmen municipality in humid forest zone at 680 m altitude. from 44 eggs produced, five progeny were reared to adulthood. during early instars they were unable to take bloodmeals directly from vertebrate hosts, but they fed successfully by cleptohaematophagy on blood from rep ... | 2000 | 10759319 |
| the ecotopes and evolution of triatomine bugs (triatominae) and their associated trypanosomes. | triatomine bug species such as microtriatoma trinidadensis, eratyrus mucronatus, belminus herreri, panstrongylus lignarius, and triatoma tibiamaculata are exquisitely adapted to specialist niches. this suggests a long evolutionary history, as well as the recent dramatic spread a few eclectic, domiciliated triatomine species. virtually all species of the genus rhodnius are primarily associated with palms. the genus panstrongylus is predominantly associated with burrows and tree cavities and the g ... | 2000 | 10904415 |
| feeding sources and natural infection of belminus herreri (hemiptera, reduviidae, triatominae) from dwellings in cesar, colombia. | belminus herreri, originally described from specimens collected in panama, was considered entirely silvatic until to 2000 when it was found for the first time in a domestic habitat in colombia. in 2001, during a new search of houses in the department of cesar, colombia, 121 specimens were collected. study of their feeding sources using an elisa test revealed that 96% of these specimens had fed on cockroaches (blattidae). however, a small proportion of these b. herreri specimens also showed the p ... | 2004 | 15250465 |
| description of the cave organ in three species of the genus belminus (hemiptera: reduviidae: triatominae) by optical and scanning electron microscopy. | the cave organ is a sensory receptor in the antenna pedicel of some reduviidae. this paper describes this organ for the first time in three species of the genus belminus, belminus corredori, belminus ferroae and belminus herreri, by optical and scanning electron microscopy. the structures presented a general pattern similar to one reported for other species of triatominae. | 2011 | 22012235 |
| demographic fitness of belminus ferroae (hemiptera: triatominae) on three different hosts under laboratory conditions. | triatominae are widely recognised for their role as vectors of trypanosoma cruzi. one of the main biological characteristics of this subfamily is their obligate haematophagous condition. however, previous studies on belminus herreri and belminus ferroae suggested that cockroaches are their principal hosts in domiciles. due to this peculiar behaviour, the aim of this study was to analyse several demographic and reproductive parameters of b. ferroae fed on three different hosts (mice, cockroaches ... | 0 | 24141961 |
